In MATLAB course homwork we asked to plot the function :

in the range [-10,10],

I plotted it with 'fplot' function, but then they wanted us to find the intersection of the function with x and y axis using only 'ginput' function, from trying and looking at the documintation there is only non accurate way to do it with your eyes and intuation (I hope you understand what I mean), there is a lot of ways to find them as i see in the internet, but we ask with the function 'ginput'.
